I have a chance to purchase a Kodak Ektragraphic 250 Slide Viewer like the one shown below off of the local Craigslist. I do have slide projectors that I use at times to view the chromes (both 35mm and 6x6). But sometimes I think I might benefit from a quick run through of the most recently developed 35mm slides. I was wondering if there are any users of this Kodak Ektragraphic 250 slide viewer. I understand that it uses a frosted glass. Is the projection on 12x12 screen nice, bright and crisp? I have never seen one working and I am all ears for your thoughts on this machine. Thanks.
